Not bad for my first attempt at (re)drawing a PCB =P
A few pages back I remember some folks complaining about hand placing 0402's...have a look at this cheap DIY pick and place:
http://vpapanik.blogspot.com/2012/11/low-budget-manual-pick-place.html even though I made one, I still ended up hand placing some of the 0402s because it was actually faster. but the pick and place helped a lot when you're really frustrated and hands are shaking.
It's running with R01F @ 4320 ohms (0.8492 V). It's using a TPS53353 (20A) regulator instead of the 30A (just a drop in replacement for the default TPS53355).
Is this board designed to go into the M-board like a normal H-board or do you have some other way of driving it?
The reason I ask is I am looking for some other way of driving a H-Board, I can't justify the cost of the M-board starter kit, it would kill the ROI on my 1 H-board setup I am currently looking for. I know some people were experimenting with driving a H-board directly and was wondering if you had conquered that?
Erk - it depends on how much DYI do you want and are capable of doing. I'm not sure how familiar are you with bitfury's chip and electronics in general so let me know if I'm being too technical - I'll try to put it in a bit more general terms below:
The Bitfury chips (fortunately) are very easy to put in a chain. On the H-card that's exactly what you have - a power converter module (to get from 12V to 0.8-0.9V at high amperage) and a bunch of chained BF chips, and the card provides (through the slot connector) pins for connecting to the previous card and also to the next card (so that you can chain cards as well). So, if you have one working device that can control (at least one) BF chip you can chain another H-card after it (and another after it, etc). All you'll need to do is hook the 3 data signals (SCK/MOSI/MISO) and 1.8V reference voltage from the "control" board to your H-card, and provide 12V to the H-Card.
If you already have means to provide the 12V (e.g. not afraid to solder two thick wires on the H-Card) then I guess the rest of your question is a "control board". The M-board is one such example. It connects to the RasPI and provides the necessary voltage conversion so that it can talk to one or more H-cards. The voltage conversion is really not much of a big deal and if you have some DYI experience you could make your own (that converts from the RasPI 3.3V to the 1.8V needed for BF chips).
If you're looking for a non-RasPI solution then any other self-contained miner (like c-scape's) could possibly be used - that one has a processor, the voltage conversion part and a bunch of BF chips, so you'll have to find the last chip in the chain and if the 3 data signals are accessible wire them to your H-Card.
Another solution would be any of the USB miners. There are several such designs (like the BiFury, RedFury and mine - NanoFury). I don't know for sure the details of the other ones (although I guess it's a similar story across all of them) so I'll speak just about my design - the NanoFury NF1 device has those 3 signals available at 3 small pads (test points). So in order to use a NF1 as the "control board" you would connect 5 wires (GND/1.8V/SCK/MOSI/MISO) from the NF1 to your H-card and then cgminer (or whatever miner you use) would detect the multiple BF chips at that port and drive them all.
